3 Claims.

This invention relates to fasteners for fabric, and it relatesparticularly to fasteners for use on sanitary belts to take and hold theends of catamenial pads or sanitary napkins.

It it the main object of this invention to provide a novel and improvedfastener of cheap and simple construction which can be used as onsanitary belts to secure the ends of sanitary pads and which will be ofa type that the napkin ends can be quickly and conveniently appliedthereto.

The objects and advantages of the invention will more fully appear fromthe following description, made in connection with the accompanyingdrawing, wherein like reference characters refer to the same or similarparts throughout the various views and in which Fig. l is a perspectiveview of a sanitary belt incorporating therein fasteners of the inventionand illustrating a sanitary pad secured by the fasteners;

Fig. 2 is a front view in enlarged scale of a portion of the belt, theend of a sanitary pad being shown in dotted lines, and

Fig. 3 is a vertical sectional view through the belt showing the partsillustrated in Fig. 2 in side elevation.

There is illustrated a sanitary belt A to which a pair of the fastenersB of the present invention are attached, and a sanitary napkin C isshown as being attached to the fasteners B.

The belt A includes a waist encircling band 4 formed of elastic fabricmaterial. Attached to the waist band 4 at diametrically opposite pointsare fabric tabs 5. Each of these tabs has an inner long arm dependingdownwardly from the waist band 4 at the inner side thereof, and it has ashorter arm depending downwardly from the waist band at the outer sidethereof. The two arms of each tab 5 are secured together and attached tothe waist band 4 as by stitching 6. Received between the two arms ofeach tab 5 and depending downwardly therefrom and attached to the tab asby the same stitching 6 is a looped strap 1 carrying a fastener B.

The fastener B of the invention is formed of flat material and isperforated to form an upper opening 8 and a lower opening 9. Between thetwo openings 8 and 9 there is formed a diamondshaped portion ID ofelongated shape and the diagonally opposite corners of thisdiamondshaped portion 10 join the outer or retaining portion I l of thefastener. The bottom of the upper opening 8 is defined by the two upperedges I2 of the diamond-shaped portion Ill and it will be seen thatthese two edges join at an obtuse angle to form a central upwardlyprojecting peak I3 in the fastener. Similarly, the top of the loweropening 9 is defined by the two lower edges M of the diamond-shapedportion Ill and these edges I4 join at an obtuse angle to form a central5 downwardly projecting peak I5 in the fastener. The lower parts of thesides of the upper opening 8 are defined by inner edges I6 of theretaining portion II which converge upwardly for some little distancefrom the lateral ends of the edges l2. With this arrangement it will beseen that the edges l2 and the edges I6 form, laterally of the peak I3,a pair of downwardly diverging triangular-shaped notches H. The anglebetween an edge I2 and an edge It is quite acute being preferablysomewhat less than 30, so that these notches H are quite pointed. Theupper parts of the sides of the upper opening 8 are defined by edges I8which respectively join the edges I6 and diverge upwardly to join thetop of the retaining portion II which is received in the looped strap 1.

The lower part of the lower opening 9 is defined by edges I9 of theretaining portion I I and these edges converge downwardly to join. Theedges I4 and the edges I9 form, laterally of the peak I5, a pair ofupwardly diverging triangularshaped notches 20 very similar to thenotches II, previously described.

In securing a sanitary pad to one of the fas- 30 teners B, an endportion of the pad, as the pad C, is carried through the upper opening 8from the inner side of the fastener; thereupon the end of the pad iscarried from the outer side of the fastener down through the loweropening 9. The pad is then pulled away from its secured end to tightlysecure it to the fastener. As the pad is pulled, the peak I3 at thelower part of the upper opening 8 cooperating with the edges I2, causesthe fabric to be carried into the two notches I1 and the fabric crowdsinto these two notches. As the fabric works down into the two notchesI'I, it is caught and held securely by the pairs of edges I6 and I2forming the notches. In much the same manner will the fabric be caughtin the notches 20 of the lower opening 9 after the lower peak I5 hascrowded the fabric into the notches 29.

After the sanitary napkin has been once attached at its two ends to thetwo fasteners B, the pad will be securely held and cannot slip or workloose from the fasteners in spite of the movements of the wearer. Thepad is very easily detached from the fastener when this is desired bymerely drawing the free end of the pad first out of the lower opening 9and then out of the upper opening 8.

It will be seen that a highly efficient fastener has been provided.Attention is called to the fact that the pad is not torn by the fastenernor are teeth employed which pass through the fabric of the pad, as inthe case of many other fasteners now in use.

It will, of course, be understood that various changes may be made inthe form, details, arrangement and proportions of the parts withoutdeparture from the scope of the invention which generally statedconsists in the matter shown and described and set forth in the appendedclaims.

What is claimed is:

l. A fastener comprising a body having an opening therethrough toreceive fabric, said opening being defined at an inner portion thereofby a peak and outwardly divergent edges of said body at either side ofsaid peak and at outer portions thereof by acute angle notches at eitherside of and spaced from said peak and provided by spaced apart,outwardly divergent side elements of said body at opposite sides of saidpeak in cooperation with outer portions of said outwardly divergentedges, the angle of divergence of said outwardly divergent edges beinggreater than the angle of divergence of said outwardly divergent sideelements.

2. A fastener comprising a body having spaced apart, oppositely disposedopenings therethrough each adapted to receive fabric, each of saidopenings being defined at an inner portion thereof by a peak andoutwardly divergent edges of said body at either side of said peak andat outer portions thereof by acute angle notches at either side of andspaced from said peak and provided by spaced apart, outwardly divergentside elements of said body at opposite sides of said peak in cooperationwith outer portions of said outwardly divergent edges, the angle ofdivergence of said outwardly divergent edges being greater than theangle of divergence of said outwardly divergent side elements in theinstance of each of said oppositely disposed openings.

3. A fastener comprising a body having spaced apart openingstherethrough each adapted to receive fabric, one of said openings beingdefined at an inner portion thereof by a peak and outwardly divergentedges of said body at either side of said peak and at outer portionsthereof by acute angle notches at either side of and spaced from saidpeak and provided by spaced apart, outwardly divergent side elements ofsaid body at opposite sides of said peak in cooperation With outerportions of said outwardly divergent edges, the angle of divergence ofsaid outwardly divergent edges being greater than the angle ofdivergence of said outwardly divergent side elements.
